Oil mills produce soybean oil, and the common processes are divided into pressing and extraction. In production, physical pressure is applied to the oil by machinery to squeeze out the oil. It is often used in oil mills or small and medium-sized edible oil processing plants. The oil content of soybeans is low, about 20%. In order to fully extract oil and increase the efficiency of the oil mill, large oil mills will use the oil extraction production process to extract soybean oil. The soybean oil extraction production process is an edible oil processing process introduced from abroad. It has a series of advantages such as high degree of automation, high production efficiency, large output, and high oil yield. It is widely used in large-scale edible oil processing projects.
The extraction process fully contacts the oil with the organic solvent, so as to dissolve the oil in the oilseed and form a mixed oil with it. Subsequently, the mixed oil is evaporated, stripped, and condensed by equipment such as evaporators and condensers, and the solvent is recovered to obtain extracted crude soybean oil. The extraction process can fully extract the oil from soybeans and obtain high-quality cakes and dregs, which can be used to extract soybean protein or process food or animal feed, etc., to improve the utilization of oil. The extraction process is widely used in the current oil processing industry.
The above are two common processes for soybean oil production. In actual production, a variety of equipment is needed to cooperate with each other to process soybean oil. According to the actual production needs of the oil mill, the equipment used in soybean oil processing mainly includes the following:
1. Pretreatment equipment
The pretreatment equipment is a process for cleaning, crushing, pressing, cooking soybean raw materials. Commonly used equipment includes vibration cleaning and stone removal machine, cooking pot, crusher, pressing machine, conditioner pot and other equipment. According to the different needs of the oil mill, the model and quantity of the equipment used vary.
2. Oil extraction equipment
The equipment for extracting oil from soybeans, commonly used equipment in industry include oil press and extraction equipment. Oil presses are widely used in oil mills and small and medium-sized oil factories. Large soybean oil processing plants mostly choose the extraction process with higher efficiency, larger processing capacity and higher oil yield. Most of the soybean oil seen on the market is finished oil produced by the extraction process.
3. Oil Refining equipment
Equipment to remove impurities from crude soybean oil, improve the quality, flavor and transparency of oil, and make it meet the standard requirements of edible oil. The commonly used refining processes for soybean oil refinery include degumming, deacidification, decolorization, deodorization, dewaxing and other main processes. The refined soybean oil has been greatly improved in appearance, quality grade, transparency, flavor and health.
The above is the classification and introduction of commonly used equipment in soybean oil processing. Oil mills should be particularly cautious in equipment selection when producing edible oil. Good equipment can provide long-term services for oil mills, improve oil yield and produce high-quality edible oil. For the purchase of soybean oil processing machine, you can consult and inspect Huatai Oil Machinery.
